One of the tickets in Trac notes that there was a copy of Keka under a different name (7z-Rar) and then goes on to state that Keka needs some kind of force of law to remain open source. What legal help is needed? There are various organizations (EFF, etc.) who can help sue organizations that copy GPL programs but don't release the source. I was just asking because I'd like to see the latest source for Keka- I want to try my hand at adding a visual user interface so that people can browse the archives and not just extract them.
